ALARM.

To all whom t may concern f l Be it known that I, ORRIE C. STROHM, a citizen ofthe United States, residing in the city of Rhiladelphia, county of Philadelphia, -State of Pennsylvania, have invented a new and useful Alarm, of which the following is a speciication.

My invention relates to a new and useful alarm for burglars and others and consists of meansfor holding a cartridge andfor means for preventing being thrown from the from the discharge.

It further consists of novel features all as will be hereinafter set forth.

For the purpose of illustrating my 1nventiOn, I have shown in the accompanying drawing one form thereof which is at present preferred by me, since the same will give in practice satisfactory and reliable results, although it is to' be understood that the various instrumentalities of which my invention consists car e variously arranged and organized and that my invention is not limited to the precise arrangement and organization of .these instrumentalities as herein shown` and described.

Figure 1 is aperspective view of an alarm device showing the same in position with -a portion of a window frame andY Fig. 2 is a sec window sash broken away.

' Fig. 1. Fig. 3

tional view' ou the line is a sectional view on the line 1f-y Fig. 2,

in detached position. Fig. 4 is an end elevation ofthe alarm in detached position.

Similar numerals of reference indicate corresponding parts in the figures.

Referrinl to the drawings, '1 designates a window sill, to which as here shown, my alarm is secured, and 2 designates is portion of a-windovv sash, which it'is to guard. The alarm comprises a lcasing 3 of any suitable construction having an, open side 4, the bottom wall 51 being adaptedA to be secured in Vany desired manner to a suitable support. ,In the drawing I have slioiign holes adapted to receive screws 6 or other fastening means for securing the`casing in position preferably with the open side 4- against a suitable portion of the window sash. Suitable means is provided for supporting the cartridge and, as shown, the upper wall 7 is provided with a suitable opening 8 adapted to receive 1and hold the cartridge 9 with the rim Specification of Letters Patent.

ably connected and, in the present Patented Dec. 5, 1916.

`Application led August 26, 1915. Serial No. 47,392.

of the head 10 thereof resting vupon said upper'wall. 11 designates a hammer which is composed of a`A resilient member, here shown as a flat spring, rotatably or swingingly mounted, as by a pivot 12, upon the upper face or wall 7 and having an end 13 extendingbeyond the end of the casing 3.

14 designates a pin cari'ied by the resilient member 11 for firing' the cartridge.

15 designates a safety device here shown as a cap or slide, which is movably or.slid' ingly mounted upon the upper wall 7 of the casing, in order that it can be moved from the opening 8 to permit insertion of a cartridge 9 and thereafter returned toV operative position said cap having in the underside of its top member a ksuitable recessv16 in which the head 10 of the cartridge is seated when the slide is in operative position.' The cap is also provided with an opening 17 which vWhen in operative position is suitably located with respectV to or'in line with the head ofv Vthe cartridge and through which the firing pinlll passes when tiring or discharging the cartridge. V i

It will be understood that the slide is suitwith or mounted upon the casing 3, in order that while being capable of being moved away from the opening` S it Icannot be detached oi' removedtherefrom instance` l have shown lugs, beads or guiding members 18 on the casing, whichare engaged by the inwardly extending flanges or ears 1) onythe slide, as will be best understood from'Fig. 3. 20 designates a stop on the casing against which the end of the slide is adapted to abut to limit its movement and to insure that it will be properly located in operative position.

21 designates a pin or other suitable abutment carried by the window sash 2 and which is normally beneath the extending end 13. of the resilient member 11.

The operation of the device is as follows :-The casing having been secured to ioov the window sill when it is desired to set the normal' position, as seen in Figs. 1 and 2, withv the firing in 14 in line with the head of the cap an with the end 13 of the member 11 extending over the pin 21. If the window sash is now elevated, the pin 21 will raise the free end 13 of the resilientA member 11 until the said pin 21 passes or releases it and, when released or tripped, the member 11 will spring down impelling the firing pin 14 forcibly against the cap striking and discharging the same. By the employment of the slide 15 it will be seen that the cap will be prevented from being thrown out of the opening 8 and it will also prevent any of the powder, wadding or products of efvplosion from injuring anyone and the smoke, etc., can escape through the open side after the cartridge is discharged through the opened window.

It will be further apparent should the cartridge be accidentally discharged by anyone improperly raising the resilient niember 11 that by reason of the construction injury to the person will be prevented. Should, through any inadvcrtence, a cartridge having a bullet therein, be placed in the device,\the closed casing and safety cap will prevent the bullet from striking or inkjurng anyone.

.It will be understood that while I have shown the device in position with respect to a window, it is, of course, applicable to doors, as well, and while I have shown the same as fconnected with the window sill, it can be otherwise supported in order to be operative.

It will no'w be apparent that I have devised a no vel and useful construction of an alarm, which embodies the features of advantage enumerated as desirable in the statement of the invention and the above description, and while I have, in the present instance, shown and described a preferred embodiment thereof which will give in practice satisfactory and reliable results, it is to be understood that the same is susceptible of modification in various partiell` seated and having an opening in line with the head when .the cap is in operative position, a stop for locating the cap in operative position, means for holding the cap and casing in propel' relation, a resilient member mounted on the casing and a firing pin carried by the member and to be actuated thereby to enter the cap-opening and discharge the cartridge.
